Like if an 18year old bloode cheerleader ran away in her handcuffs, then they tazed her, would they then catch up then kick her in the head and beat her for several minutes?
I personally don'tn think that would happen.
That's more likely to be down to her being female than being blonde (and presumably by implication white?).
I suspect a Latino or white guy of the same age, same socioeconomic background, driving the same car, wearing the same clothes and in the same neighbourhood would be treated in the same way by those same officers if, upon being stopped, he ran off and they had to chase him...
In rough neighbourhoods police in the US are prone to being more aggressive and the biggest factor here is likely the chase.
